I just started playing with Linux, I have a question. I'm running Knoppix from a bootable DVD, I have a 22" LCD monitor, how do I set the display resolution to 1680X1050? 1680X1050 is the native resolution of my screen. My video card is a ATI HD4850.

For most users it won't be necessary to go into installation and configuration details of the driver. Ubuntu 8.04 (Hardy) provides a notification saying that there are restricted drivers available. You just have to go there (Restricted Drivers Manager) and enable the "ATI accelerated graphics driver". Ubuntu will then install and configure the driver for you. If this does not provide the optimal solution you were looking for, please read ahead"

I did not know about the "Restricted Drivers Manager" I will try this next.
